Mr. Silverstein was serving three consecutive life terms for the killing of two fellow prisoners and a guard while behind bars. He had been incarcerated continuously since 1975, originally on an armed robbery conviction. He was said to have joined the Aryan Brotherhood, the white nationalist prison gang, while serving time at Leavenworth Penitentiary in Kansas.
He was in solitary confinement for 36 years, more than half his life. The American Civil Liberties Union has cited his case in its campaign against long-term solitary confinement.

In 1981, Mr. Silverstein and another inmate, Clayton Fountain, were convicted of murdering Robert Chappelle, a member of the D.C. Blacks prison gang. During the trial, the gang’s national leader, Raymond (Cadillac) Smith, was transferred to Marion, apparently intent on killing Mr. Silverstein in revenge. (Prison officials, Mr. Silverstein said later, were aware of the threats but “didn’t take any action to make me safe.”)
Mr. Silverstein and Mr. Fountain got to Mr. Smith first, stabbing him 67 times with makeshift weapons, then dragging his body along prison catwalks as an object lesson. Mr. Silverstein received two more life sentences, for the murders of Mr. Chappelle and Mr. Smith. He insisted that he was innocent of the Chappelle murder and that he had killed Mr. Smith in self-defense.
By 1983 Mr. Silverstein had taken up art, teaching himself and becoming accomplished at it. One day, on his way back from showering, another prisoner handed him another makeshift knife and a homemade key. Using it, he managed to unlock his handcuffs and then fatally stabbed Merle E. Clutts, an unarmed correction officer, about 40 times.
His running buddy Mr. Fountain killed another guard that same day. These incidents are (at least in part) what prompted the construction of the SuperMax prison in Colorado.
Mildly interesting fact that I ran across last night: Clayton Fountain, who was also confined in solitary, took theology courses, converted to Catholicism, and was accepted as a lay brother by a Trappist order after his death.
